POINTER ** 501 PIX.. Changed Outside IP.. Client Side VPN Not Working

Hey guys, we just switched ISPs and all is well except for client side VPN. First off, the clients are using a DNS name to connect and are resolving correctly to our new outside IP.

I have heard mixed reviews that the public IP info is somehow built into the encryption algorhytm. So if your outside IP changes, you must reconfigure VPN on the PIX. Is there any truth to this? I can't figure out what else it could be. All I did was change the outside IP and default route.

6.3(3) is very buggy and a hard power off reboot might take care of the situation.
Yes, you need SmartNet support to get updated OS, or you can buy a 1-time upgrade but it might cost more than a full year of maintenance.
